3D Automated Breast Ultrasound System: Comparison of Interpretation Time of Senior Versus Junior Radiologist

Abstract

Objective: This study aimed to compare the automated breast ultrasound system (ABUS) reading time of breast radiologist to a radiology residentindependent of the clinical outcomes.Materials and Methods: One hundred women who underwent screening ABUS between July and August 2017 were reviewed retrospectively.Each study was examined sequentially by a breast radiologist who has more than 20 years of experience in breast radiology and third year residentwho has 6 months of experience in breast radiology. Data were analyzed with Spearman' correlation, Wilcoxon Signed Ranks Test and Kruskal-WallisTest and was recorded.Results: The mean age of patients was 42.02±11.423 years (age range16-66). The average time for senior radiologist was 223.36±84.334 seconds(min 118 max 500 seconds). The average time for junior radiologist was 269.48±82.895 seconds (min 150 max 628 seconds). There was a significantdifference between the mean time of two radiologists (p=0.00001). There was a significant difference regarding the decrease in the reading timethroughout study with the increase of number of cases read by the breast radiologist (p
